Earlier this month, The CW released a stylish promo teaser celebrating their hit DC Comics series “Arrow” and “The Flash” wherein all the shows’ super heroes battle all the shows’ villains. Since then, we’ve been getting regular updates in a similarly themed set of character posters. The latest one has just arrived and, in the gallery viewer below, you can check out the full design featuring Katie Cassidy’s Laurel Lance, aka Black Canary!

This week’s episode, 3.21, is titled “Al Sah-him” and is officially described as follows:

“Oliver (Stephen Amell) goes through a rigorous transformation. The League of Assassins sets their sites on Nyssa (guest star Katrina Law), who is back in Starling City training Laurel (Katie Cassidy). When Nyssa realizes they are coming, she arms up to face them alone but Laurel asks Felicity (Emily Bett Rickards) and Diggle (David Ramsey) to help protect her new friend.”

Directed by Thor Freudenthal with story by Beth Schwartz and teleplay by Brian Ford Sullivan & Emilio Ortega Aldrich, “Al Sah-Him” is set to air this Wednesday, April 29. After that’s there’s just two episodes left in the show’s third season.
